The adjustment may include a set of changes not exceeding 20% of the total time that was spent on the realization of the task. For example, as revision you can replace the piece of furniture, change the color of the walls, and add decorations. The adjustment may not include a change of style (it was high-tech, change to the classics), may not include a change of room (it was a bedroom, change to an en-suite) etc. Each revision is treated individually based on the volume of work. Some changes could be made for half the standard cost, some – as double editing, some – for free.
